Transient variable can't be serialize.A volatile variable is not allowed to have a local copy of a variable that is different from the value currently held in "main" memory.

volatile modifier requests the Java VM to always access the shared copy of the variable so the its most current value is always read. If two or more threads access a member variable, AND one or more threads might change that variable's value, AND ALL of the threads do not use synchronization (methods or blocks) to read and/or write the value, then that member variable must be declared volatile to ensure all threads see the changed value.when you don't want to serialize a member variable then you define that variable as transient.

Transient modifier applies to variables only and it is not stored as part of its objects persistent state.

Volatile modifier applies to variables only and tells the compiles that the variable modified by volatile can be changed unexpected by other parts of the programe.

transient means witch variable you don't want to be serializable put that variable as transient and volatile variable is variable witch is always changing its value,but its depreciated no use of it,

The transient modifier applies to variables only and it is not stored as part of its object’s Persistent state. Transient variables are not serialized. Volatile: Volatile modifier applies to variables only and it tells the compiler that the variable modified by volatile can be changed unexpectedly by other parts of the program.

If you are working with the multi-threaded programming, the volatile keyword will be more useful. When multiple threads using the same variable, each thread will have its own copy of the local cache for that variable. So, when its updating the value, it is actually updated in the local cache not in the main variable memory. The other thread which is using the same variable doesnt know anything about the values changed by the another thread. To avoid this problem, if you declare a variable as volatile, then it will not be stored in the local cache. Whenever thread are updating the values, it is updated to the main memory. So, other threads can access the updated value.

transient variable is the variable which cant be serialized..volatile is useful in multi thread env.each thread has ots own copy to update..in fact it wont update the main memory var ..its update the local cache so if ..it update the main memory only after the completing operation so ..new thread will get the updated value
